Description
Technical Field
The invention relates to the technical field of heat dissipation devices, in particular to a double-cavity piezoelectric jet active heat dissipation device and a terminal.
Background
With the increasing functions of the portable equipment due to the continuous reduction of the volume of the portable equipment, the power consumption of the equipment is increased, and the loss is increased, so that the central processing unit generates heat; higher heat may result in electrons at higher energy levels, reducing the cpu operating speed. In order to solve the problem of high heat dissipation and high heat consumption of the existing active heat dissipation, in 2012 at 6 th European thermal science conference, a piezoelectric active heat dissipation device is disclosed by the general electric global research and development center HPJDeBock and the like: while the piezoelectric wafers actuated in opposite directions and the single-opening cavity form an airflow generator. Hereinafter, there are subsequent papers describing improved piezoelectric jet active heat dissipation devices. For example, ahmad Jalilvand et al from Japanese vine warehouse, 2014, journal of thermal and engineering applications (journal of THERMAL SCIENCE AND ENGINEERING applications) writing articles addressed the problem of improving the heat dissipation efficiency of piezoelectric jet fans. On the basis, we propose a thin, large-blast volume and possess the low initiative heat abstractor of two-chamber piezoelectric jet at the same time of noise.
With the increasing functions of the portable equipment due to the continuous reduction of the volume of the portable equipment, the power consumption of the equipment is increased, and the loss is increased, so that the central processing unit generates heat; higher heat causes the electrons to be at a higher energy level, and the cpu operation speed decreases, so heat dissipation becomes a key technology.
The existing heat generating devices, such as a central processing unit, generally adopt a heat dissipation mode of a fan, however, the fan has the technical problems of large volume, high power consumption and poor heat dissipation effect.
Therefore, there is a need to develop a heat dissipating device with good heat dissipating effect for portable devices.

Example 1
Referring to fig. 1 and 2, the present embodiment provides a dual-cavity piezoelectric jet active heat dissipation device, which includes:
at least one jet unit 100, the jet unit 100 including a first piezoelectric vibrator 110 and a second piezoelectric vibrator 120 symmetrically arranged;
each of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 includes a substrate 101 and a piezoelectric body 102 attached to the substrate 101;
The piezoelectric body 102 of the first piezoelectric vibrator 110 and the piezoelectric body 102 of the second piezoelectric vibrator 120 are both arranged outwards, a cavity 103 is formed between the substrate 101 of the first piezoelectric vibrator 110 and the substrate 101 of the second piezoelectric vibrator 120, and one end of the cavity 103 is opened;
The first and second piezoelectric vibrators 110, 120 move back to draw air into the chamber 103 and move toward each other to expel air, thereby forming a jet.
The beneficial effects that the double-cavity piezoelectric jet active heat dissipation device that this embodiment provided can reach are analyzed as follows:
Since the present embodiment provides a dual-cavity piezoelectric jet active heat dissipation device, the dual-cavity piezoelectric jet active heat dissipation device includes at least one jet unit 100, where the jet unit 100 includes a first piezoelectric vibrator 110 and a second piezoelectric vibrator 120 that are symmetrically disposed. Each of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 includes a substrate 101 and a piezoelectric body 102 attached to the substrate 101. The piezoelectric body 102 of the first piezoelectric vibrator 110 and the piezoelectric body 102 of the second piezoelectric vibrator 120 are both disposed outward, a cavity 103 is formed between the substrate 101 of the first piezoelectric vibrator 110 and the substrate 101 of the second piezoelectric vibrator 120, and one end of the cavity 103 is opened.
As can be seen from an analysis of the above-described structure, when the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 move backward, the volume of the cavity between the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 increases, and external air enters the cavity, thereby achieving the effect of air suction. Subsequently, the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 move toward each other, and gas in the cavity is pressed during the opposite movement, so that the gas is discharged, thereby achieving an exhaust effect. The continuous operation of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 allows the device to continuously suck and discharge air, and the discharged air can dissipate heat from other devices (e.g., a central processing unit). Because the piezoelectric body 102 adopted in the embodiment can be smaller, the volume of the product can be greatly reduced, and the piezoelectric body 102 can realize continuous operation under the action of current, so that a good heat dissipation effect can be ensured.
The operation principle of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 is described as follows:
When the piezoelectric material is polarized in an electric field, the material is deformed due to displacement of the charge center. Interconversion of mechanical vibrations (acoustic waves) and alternating currents can be achieved by utilizing these properties of the piezoelectric material. Piezoelectric materials are thus widely used in sensor elements, such as seismic sensors, force, velocity and acceleration measuring elements, and electroacoustic sensors. The first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 in this embodiment realize a continuous vibration effect under the action of alternating current, and the matching of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 can increase or decrease the cavity volume. Specifically, when the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 move toward each other, the cavity volume is reduced, and when the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 move away from each other, the cavity volume is increased.
In an alternative to this embodiment, the first and second embodiments, preferably,
An internal support frame 130 is further provided between the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120, and a top end of the internal support frame 130 is opened, and a bottom end is used for sealing a bottom end of the chamber 103. The internal support frame 130 serves to support the first and second piezoelectric vibrators 110 and 120.
In an alternative to this embodiment, the first and second embodiments, preferably,
Two jet units 100 are provided, the two jet units 100 being arranged side by side with the openings facing the same side. Further, when one of the jet units 100 sucks air, the other jet unit 100 discharges air, so that the device can always discharge air and dissipate heat.
In an alternative to this embodiment, the first and second embodiments, preferably,
The outer sides of the two fluidic units 100 are provided with an outer side support frame 140. The outer support frame 140 serves to support the plurality of fluidic units 100 to form a complete structure.
In an alternative to this embodiment, the first and second embodiments, preferably,
The substrate 101 may be made of metal, carbon fiber, glass fiber, etc. with good elastic deformation, and the substrate 101 vibrates under the vibration action of the piezoelectric body 102.

The thickness t of the substrate 101 satisfies: t is more than 0.08mm and less than 0.16mm.
In an alternative to this embodiment, the first and second embodiments, preferably,
The thickness ratio of the piezoelectric body 102 to the substrate 101 is: 1.0 to 1.2.
An example:
In this embodiment, an example is shown in fig. 3:
Double-cavity piezoelectric jet fan: the total thickness was 2.85mm.
Wherein the thickness of the substrate is 0.11mm, the thickness of the piezoelectric body is 0.11mm, the thickness of the outer support frame is 0.25mm, the thickness of the inner support frame between two adjacent substrates of the first jet unit and the second jet unit is 0.7mm, the thickness of the inner support frame on the left side of the second jet unit is 0.5mm, the driving power is 0.009W, and the flow rate is 0.47 cubic feet per minute.
It is apparent that the jet fan in this example had a thickness of 2.85mm, a drive power of 0.025W, and a flow rate of 0.47 cubic feet per minute. In the prior art, the current ultra-thin notebook computer is exemplified by the standard 3004 fan, wherein the thickness of the 3004 fan is 3mm, the driving power is 0.025W, and the flow is 0.4 cubic feet per minute.
The jet fan provided by the embodiment has the advantages of reduced thickness, reduced driving power and increased flow, so that a better heat dissipation effect can be realized.
Example 2
Referring to fig. 4 and 5, another dual-cavity piezoelectric jet active heat dissipation device is provided in this embodiment, which is similar to embodiment 1, and includes at least one jet unit 100, where the jet unit 100 includes a first piezoelectric vibrator 110 and a second piezoelectric vibrator 120 that are symmetrically disposed. Each of the first piezoelectric vibrator 110 and the second piezoelectric vibrator 120 includes a substrate 101 and a piezoelectric body 102 attached to the substrate 101. The piezoelectric body 102 of the first piezoelectric vibrator 110 and the piezoelectric body 102 of the second piezoelectric vibrator 120 are both disposed outward, a cavity 103 is formed between the substrate 101 of the first piezoelectric vibrator 110 and the substrate 101 of the second piezoelectric vibrator 120, and one end of the cavity 103 is opened. The first and second piezoelectric vibrators 110, 120 move back to draw air into the chamber 103 and move toward each other to expel air, thereby forming a jet.
Further, an intermediate substrate 150 is provided in the middle of the fluidic unit 100, the intermediate substrate 150 dividing the chamber 103 of the fluidic unit 100 into a first sub-chamber 103 and a second sub-chamber 103.
When the first piezoelectric vibrator 110 moves in a direction away from the intermediate substrate 150, the volume of the first sub-chamber 103 increases, and the gettering effect is achieved. When the first piezoelectric vibrator 110 moves in a direction approaching the intermediate substrate 150, the volume of the first sub-chamber 103 is reduced, and an exhaust effect is achieved, and under the action of alternating current, the first piezoelectric vibrator 110 continuously sucks and exhausts the first sub-chamber 103 through vibration.
When the second piezoelectric vibrator 120 moves in a direction away from the intermediate substrate 150, the volume of the second sub-chamber 103 increases, and the gettering effect is achieved. When the second piezoelectric vibrator 120 moves in a direction approaching the intermediate substrate 150, the volume of the second sub-chamber 103 is reduced, and an exhaust effect is achieved, and the second piezoelectric vibrator 120 continuously sucks and exhausts the second sub-chamber 103 by vibration under the action of alternating current.
As can be seen from the above analysis, the piezoelectric body 102 used in the present embodiment can be smaller, so that the volume of the product can be greatly reduced, and the piezoelectric body 102 can realize continuous operation under the action of current, so that a good heat dissipation effect can be ensured.
